Calcium pyrophosphate dihydrate deposition disease is a joint disorder in which calcium crystals build up within the joints, which can cause inflammation. It is also known as pseudogout.

Common symptoms: Episodes of pain, swelling, and redness of a joint, with the knee being one of the most affected; at times it causes more constant discomfort similar to other forms of arthritis.

When to see a doctor? Intense joint pain of sudden onset or recurring joint discomfort deserves an evaluation.

Which specialist treats it? The rheumatologist is the professional who studies crystal disorders and joint diseases. If you experience repeated flares of joint inflammation, having a specialist evaluate it helps determine the cause and guide follow-up.
